I mean, yes, but I'm not sure I see your point. The Harvard vs Von Neumann architectural difference is more related to the number of AHB ports on the core. > That doesn’t apply to smartphones, PCs or servers even in the intel world due to instruction caches etc… I wouldn't confuse instruction caches with Harvard vs Von Neumann either - loads of Von Neumann machines have instruction or Flash caches too. It's also not uncommon to run into Von Neumann cores in mobile and PC chips, just as peripheral co-processors. It is just middle aged guy who did this stuff for years...
